### Toolchains
This project makes use of Maven toolchains to ensure that the correct Java compiler version is used when compiling source files.

-##### Motivation
+### Motivation
Toolchains are used in different maven modules to ensure that the correct Java compiler version is used when compiling source files. This is because `datasketches-memory` uses some JDK version-specific APIs, which require different JDKs to compile correctly.
-##### Toolchain template
+### Toolchain template
Your local environment requires toolchain entries for Java 8, 9 and 11 to build this project. These can be found in a reference `toolchains.xml` template in the `tools` directory.
Any maven commands used during development can be supplemented with: `--toolchains tools/toolchains.xml`, without permanently modifying a local `~/.m2/toolchains.xml` file (recommended).
Alternatively, the toolchain template can be copied to your local maven `toolchains.xml` e.g. `~/.m2/toolchains.xml`. If there is already a locally configured `toolchains.xml` file, the requisite entries should be merged into the existing file if they do not already exist.
-##### Environment variables

If you are an Eclipse user, you may need further configuration for your IDE to use the appropriate JDK for each module - see the [eclipse IDE setup](eclipse.md).

Java versions 9 and above. Therefore, a multi-module project allows us to add support for later versions of
Java by using independent Maven modules to target platform-specific APIs. For example, to deallocate references
a `sun.misc.Cleaner` will be used in Java8, but the `jdk.internal.ref.Cleaner` is used in Java 9.
